Answer:
The middle child
Step-by-step explanation:
Most times this is how the scenario plays out, the oldest child is more like the boss and feels powerful owing to the high expectations often set by the parents. A lot of times the parent saddle them with a lot of responsibilities especially low paid parents.
While the youngest child is treated like a spoiled baby and can never rise above the other siblings. Probaly given anything they want
The middle child is even-tempered but has trouble fitting in due to being sandwiched between the younger and older siblings.

Middle children's characteristics
Below are some common ideas about the characteristics of middle children.
Rivalry
The need to compete with both the younger and older sibling for parental attention is something the middle child goes through. They might compete for attention between siblings, as they risk being ignored by one or the other. As they find themselves in the middle of everything, they may also become the peacemaker.
Favoritism
Middle children generally don’t feel that they are the favorite child of the family and most times they are not. Favoritism may exist for the oldest child who is viewed as special and their firstborn which the parents might have waited for, or for the youngest child who is viewed as the baby. The middle child falls somewhere in-between and is unable to be the favorite of either parent.
